PRECAUTION
PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS004MP
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Components Parts and Harness Connector Location
AKS004MS
System Description
AKS004MT
●
All front wiper relays (HI, LO) are included in IPDM E/R.
●
Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.
●
BCM (body control module) controls front wiper LO, HI, and INT (intermittent) operation.
●
IPDM E/R (intelligent power distribution module engine room) operates wiper motor according to CAN
communication signals from BCM (body control module).
Power is supplied at all times
●
to ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]
●
through 50 A fusible link (letter F, located in fusible link block)
●
to BCM (body control module) terminal 55
●
through 10 A fuse [No. 18 located in fuse block (J/B)]
●
to BCM (body control module) terminal 42
●
through 30 A fuse [No. 73 located in IPDM E/R (intelligent power distribution module engine room)]
●
to front wiper relay [located in IPDM E/R (intelligent power distribution module engine room)]
●
through 15 A fuse [No. 78 located in IPDM E/R (intelligent power distribution module engine room)]
●
